With the win the Huskies (47-11) lead the series 1-0 and stand one win away from the 12th Women's College World Series appearance in program history and first since 2013.
The Huskies roughed up the Utah pitching duo of Miranda Viramontes (14-4) and Hailey Hilburn for 10 runs on 14 hits and six walks, with the first five batters -Ali Aguilar, Sis Bates, Casey Stangel, Flores, and Taylor Van Zee getting 11 of the hits and producing all the runs.
In the bottom of the first Aguilar led off with a walk and Bates beat out an infield single to short. Stangel grounded a single to right to score Aguilar for a 1-0 lead and her first RBI of the postseason.
Flores made it 4-0 when she drilled a line drive over the wall in left field for a three run homer, her 11th of the season. The home team made it 5-0 in the second with two outs when Aguilar walked, moved to second on a single by Bates, and scored on a double to left center by Stangel.
The Utes (36-15) cut the Husky lead to 5-3 in the top of the fourth. Hannah Flippen led off with a single and one out later Bridget Castro singled. With two outs, Kelly Martinez drove a 3-2 pitch from Taran Alvelo (32-6) into the right center field bleachers for a three run homer, her seventh of the season.
Washington came right back in the home half of the fourth with four runs to break the game open.
Aguilar led off with a double over the head of right fielder Alyssa Barrera. Bates and Stangel walked to load the bases and bring Flores to the plate. The crowd rose to its feet in anticipation of what Flores might do in this particular at-bat. She looked at ball one and then fouled the next pitch off the screen by the first base dugout for strike one.
After taking two more balls to make the count 3-1, Flores took Hilburn deep beyond the wall in left field for a grand slam, her 12th long ball of the season, and a 9-3 Husky lead.
Van Zee increased the lead to 10-3 in the sixth with a leadoff homer, her seventh, over the bleachers in right center field.
The Utes made it 10-4 in the top of the seventh when they loaded the bases and Martinez scored on a fielder's choice groundout by Barrera.
In the circle for the Huskies, Alvelo went the distance for the complete game. She gave up four runs, all earned, on eight hits. She walked one and struck out one.
Game 2 of the series will begin around on Saturday, May 27.
